Your boss doesn't really trust either of the other two forecasts from the consultant, so she supplies her own forecasts as follows:

States	Probability of Occurrence	Investment Returns
State 1: Economic boom	18%	20%
State 2: Economic growth	42%	16%
State 3: Economic decline	30%	3%
State 4: Depression	10%	-25%

	a.	8.72%, 12.99%
	b.	7.35%, 12.99%
	c.	3.50%, 1.69%
	d.	2.18%, 1.69%
